We have also put together [an FAQ document](https://knowledge.yorkland.net/hubfs/JACE%202022%20Changes%20FAQs.pdf?hsLang=en) to address typical follow-on questions. Tridium is alerting the Niagara Community to these upcoming changes and the resulting N4 licensing timeline so that you can take any necessary actions to minimize the impact on customers.     ![N4Timeline](https://knowledge.yorkland.net/hs-fs/hubfs/N4Timeline.png?width=688&name=N4Timeline.png)  ***Summary:*** As Tridium continues to maintain and update the JACE 8000 platform, certain changes in firmware and hardware have been necessary. With the Niagara 4.8 release, Tridium moved away from Oracle as its JACE 8000 Java provider to Azul. To complete this transition, Tridium will end support of Oracle Java on JACE 8000 on November 29, 2022. ***Impact:*** Tridium will no longer be able to sell N4 licenses that will permit running a version below 4.8 for JACE 8000. There will be no impact to existing licenses or hardware running lower versions. Warranty and RMA replacement for already licensed JACE 8000s will not be impacted. Niagara 4 Supervisor licensing and permitted versions will not be impacted by this change. **Change in Micro-SD Card Provider** ***Summary:*** JACE 8000 currently uses a micro-SD card that is near its end of life, so Tridium will be phasing in a replacement. The new micro-SD card will only support Niagara version 4.9u1 and higher. This change in providers is anticipated to take place in Q1 of 2023 by approximately February 1. ***Impact:*** After this change is implemented, JACE 8000s shipped from Tridium will not run any Niagara versions lower than 4.9u1. These changes do not affect the ability of existing JACE 8000s to run older Niagara versions or to upgrade to the latest version. This change has no impact on licensing or host-id schemes. Note: There will be a stock of the previous version of micro-SD cards reserved for RMAs and replacement. **Factory-Restore Version Update** ***Summary:*** As a result to these Java and Micro-SD Provider changes, Tridium updated the f*actory-restore* version to Niagara 4.9u1 in Q2 2022. This change was rolled out across all factory-installed images, including OEM-specific and appliance images. ***Impact:***This update to the factory-restore version of Niagara should have no impact on the normal process of commissioning a JACE sent from the factory to Niagara 4.9u1 or higher. If there are special circumstances that require JACE commissioning to a version lower than 4.9u1, there is a ***clean dist*** routine available until November 29, 2022.
